The SiT8919B extends frequency support up to 137 MHz while maintaining excellent stability (±20 ppm) at high temperatures (up to 125 °C) in the smallest 2.0 x 1.6 mmxmm package, a combination that is not readily available from quartz. This device also features the industry's best vibration sensitivity, and shock and vibration resistance.

The SiT8919 comes in industry-standard packages and footprints, and therefore replaces quartz without any design changes.

For the same device in a SOT23-5 package, refer to the SiT2019B.
